1. During installation, the butterfly plate of the stainless steel butterfly valve must be stopped in the closed position.
2. The opening position must be determined according to the rotation angle of the butterfly plate.
3. For stainless steel butterfly valve with bypass valve, the bypass valve must be opened before it can be opened.
4. The installation must be carried out in accordance with the manufacturer's installation instructions. Heavy-duty stainless steel butterfly valves should be installed on a solid foundation.
5. The butterfly plate of the stainless steel butterfly valve is installed in the radial direction of the pipeline. In the cylindrical passage of the valve body, the disc-shaped butterfly plate rotates around the axis with a rotation angle of 0°～90°. When the rotation reaches 90°, the valve is fully opened.
6. If you need to use a butterfly valve as a flow control, it is mainly to choose the appropriate valve size and type. The structural principle of the butterfly valve is particularly suitable for the manufacture of large-diameter valves. Butterfly valves are not only widely used in petroleum, natural gas, chemical, water treatment and other general industries, but also widely used in cooling water systems of thermal power plants.
7. Commonly used butterfly valves include wafer butterfly valves and flanged butterfly valves. Wafer butterfly valves use stud bolts to connect the valve between two pipe flanges. Flanged butterfly valves have flanges on the valve, and bolts are used to connect the flanges at both ends of the valve with the pipe flanges.
8. The butterfly plate of the butterfly valve is installed in the radial direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is 0°～90°. When the rotation reaches 90°, the valve is fully opened.
